5. IN AN AUTOMATIC COMMUNICATION SYSTEM, A PLURALITY OF COMMUNICATION CIRCUITS EACH HAVING AN IDENTIFYING DESIGNATION, CONTROL MEANS FOR ESTABLISHING COMMUNICATION PATHS BETWEEN CALLING AND CALLED ONES OF SAID CIRCUITS IN DIFFERENT TIME POSITIONS IN A REPETITIVE TIME FRAME, SAID CONTROL MEANS INCLUDING BOTH A PLURALITY OF FIRST SIGNAL CIRCULATING MEANS FOR CIRCULATING SIGNALS REPRESENTING THE DESIGNATIONS OF SAID CIRCUITS AND GATE MEANS CONTROLLED BY SAID PLURALITY OF FIRST SIGNAL CIRCULATING MEANS, AND A SECOND SIGNAL CIRCULATING MEANS FOR CIRCULATING SIGNALS IN SAID DIFFERENT TIME POSITIONS FOR RENDERING SAID GATE MEANS RESPONSIVE TO CONTROL BY SAID PLURALITY OF FIRST SIGNAL CIRCULATING MEANS IN SELECTED ONES OF SAID TIME POSITIONS.
